Note:Im helping 4_seven as beta tester on "LastX" and "First[attachment]" (my guru-he is a bad coder )..and i help with modX for these.
-He does all the php coding for Last X and First[Attachment]....and many more
-He also did a First [img]...for the [img] BBcode

me to on all my forum..but to be as barebones i do not want that change in .css (better users tweak i think)

The bbcode is made in the ACP>Posting>BBCodes. Just create the bbcode using this:

oki, now i see.. but bbcode dosnt make a thumbnail. It just shows the image full size, thats why people use mod like Reimg Resize. I have tried this mod but it have load issues(same as your bbcode) and dos not resize (make a thumbnail), it just shows the full image fitted=HUGE load time when 2-4 images.
I have discussed this issue with other bad coders..and they say phpbb will have limit issues to make a script that makes thumb to resizes remote url images.Highslide need thumb and image src. And i dont think bbcode allows script. A Thumbnail Script is needed i think, but this is extream hard and maybe impossible.
With your highslide BBcode It just shows the image fullsize, no thumb is created with bbcode.So if user url to a ex 3000x3000px img...your bbcode [highslide] will show the full size image in div with ex 320px..meaning loadtime will be the same as looking at img fullsize...You folloW??

I have asked for a BBcode or mod like you are trying too..but its a dream i think..
Instead of [img] or your [highslide]..I tell my users to download whatever image from whatever page, and THEN-> upload image to forum from their pc... with attachment in phpbb
..but a BBcode [highslide] with thumbnail creation for remote image URL... would be extream nice and a dream for me too

Anyway, i think what your stating. It may be 320px on the post, but the forum actually loads the entire fullsize image? If so, that is an unnecessary load and will consider removing that option entirely and just use attached images.
